‍What you’ll learn in this episode

Why battery energy storage systems (BESS) are now essential

Discover how the energy landscape has shifted from focusing solely on solar panels to prioritizing battery storage systems. Mauricio Olmos, Senior PV and BESS Expert at Huawei, explains why the battery has become the “star” of the system – helping homeowners store excess solar power, reduce costs and achieve greater energy independence.

How PV, HEMS and BESS work together

Learn how pairing PV systems with home energy management systems (HEMS) and batteries creates a smarter, more dynamic setup. Mauricio breaks down how HEMS software optimizes when energy is bought, stored, or used – maximizing savings and improving efficiency.

The evolution of the best battery storage systems

From early lead-acid batteries to today’s advanced LFP technology, efficiency and lifespan have skyrocketed. Mauricio shares how innovations in battery energy storage systems (BESS) now deliver 90% efficiency, 30-year lifespans and rapidly falling costs – making clean energy more accessible than ever.

What’s next for energy storage and smart grids

Look ahead to the rise of virtual power plants, bidirectional EV charging and large-scale BESS deployments. Mauricio outlines how these innovations will strengthen grid stability, enable peer-to-peer energy exchange and redefine how consumers and utilities manage power.

Key quotes: The battery is now the star of the system.

“Technology alone isn’t enough. With PV, HEMS and BESS working together, you create a truly smart and efficient energy system.”

“The battery is now the star of the system. Solar panels just produce energy – the battery makes it usable.”

“Efficiency has doubled, costs have dropped and batteries can now last 30 years – that’s the real revolution in energy.”
